have an appt tomorrow with a company that does these. The owner was in buying a box blade this weekend. she told me some great stories on how they used the cameras to catch crooks and stopped thier break ins (they do home theater and steros so a prime target). They had one video that by thier description, should have been sent to one of those dumb crook shows, smashed the glass door, came in a loaded up on equipment, ran out the door but hit their head on teh push bar, merchandise flying, crook out cold a few moments, then up and ran (blood all over from scalp laceration) clear picture of license plate both backing up to the door and leaving. arrested the next morning. Looking forward to similar. I thought about lo jacks on some units but hard to tell which one they will steal. Booby traps unfortunately come with some goofly legal ramifiactions, plus our weekend shoppers might get an unwelcome surprise as the lot is open, just has a low pipe fence around to prevent theft (padlocks only keep honest people honest, assuming the chicken SxxTs that stole the tractor were not honest before they cut the lock, if they were the padlocks served no purpose at all).
